Which hazard intensity increases when fine tephra accumulates?

💡 Explanation

Agricultural productivity suffers if tephra blankets essential local farmland; this is caused by direct inhibition of photosynthesis because tephra blocks sunlight. Therefore agricultural decline increases rather than oceanic acidity, glacial melting, or tsunami reduction, which relate to ashfall into aquatic systems or atmospheric darkening, not ground visibility.
